Abstract: 1. Method for the regulation and current limitation of a direct current ringing choke converter by means of a pulse-width-controlled electronic switch (6), which is periodically ignitable under external control and extinguishable in dependence on a comparator signal, wherein a reference voltage (Uref) and an evaluation signal are compared for the formation of the comparator signal and wherein the evaluation signal is formed from the sum of a signal for the output magnitude to be regulated and a signal which is supplied by a current converter (10) which transforms the total current through the electronic switch, characterised thereby, that a unidirectional voltage value, which is proportional to the peak value of the total current through the electronic switch (6) and which is obtained by peak integration of the current converter output signal, serves as signal for the output magnitude to be regulated.

Abstract: A filter network that exhibits a bandstop response comprises a network of basically low-pass or high-pass structure. The network is developed by choosing a bandstop transfer function, a fourth-order elliptic is disclosed, which is converted to a low-pass function.

Abstract: A signal of a predetermined frequency is injected into the served (insulated) sheath of an underground cable and the resultant magnetic  H  field generated is monitored using two pick-up coils 62 and 63 aligned along the length of the cable. The phase difference between the emfs induced in the two coils is a measure of the  H  field gradient and a sharp change in phase accompanied by a change in emf. magnitude indicates a fault. The same two coils turned through 90° transversely to the cable can be used to locate the cable by scanning transversely to the cable. As the coils pass over the cable the relative phase of the induced emf signals in the coils reverses. Alternatively, three or four coils may be used arranged in two orthogonal pairs with the coils of one pair being aligned in use along the cable and the coils of the other pair transverse to the cable.

Abstract: When aqueous solutions of a metal cyanide complex are detoxified with hydrogen peroxide, a residue of cyanide remains, which in the case of nickel for example may be present as Ni(CN) 2 . In a process according to the present invention the detoxification of aqueous alkaline solutions of a metal cyanide complex is carried out using a restricted amount of certain complexing agents together with the hydrogen peroxide. A particularly suitable example of such complexing agents is ethylenediaminotetraacetic acid. It is especially preferred to use the complexing agent in a mole ratio to metal of from 0.8:1 to 1.5:1, together with hydrogen peroxide in a mole ratio to cyanide of from 2:1 to 3:1. The process is well suited to the treatment of concentrated solutions of cyanide, in many cases at least 4000 ppm, for example those resulting from the stripping of nickel plating.
